Lab-created and Treated Gems

The Lab-created and Treated Gems workshop, developed by the WGF (World Gem Foundation), is devoted to the practical identification of lab-created and treated gemstones.

This five-day workshop includes practical instruction on how to identify lab-created coloured gemstones with particular emphasis on rubies, sapphires and emeralds. Students will also learn how to detect treatments and enhancements commonly used to improve the appearance of coloured gemstones.

This will allow you to compare and determine if a stone is natural, lab-created or treated.
